We moved, and just received (at day 31 after move out) a certified letter stating that we had $7100 worth of smoke damage in the apartment "pending additional charges to be determined".   

Learned that unless you make justify an increase in price, the additional just isn’t worth it.

In addition, this is a C class apartment, where would you spend your focus and money to raise value?

Most companies will max out at $500k then you need to rely on an umbrella policy for additional coverage.

Other than it being a additional cost to do business and financing being more difficult under a LLC as long as you have adequate insurance coverage there is little other difference. 

@Jimmy ReadyYou can contribute up to $5,500 to an IRA per year and this is an addition to being able to contribute to your employer 401k plan. https://www.irs.gov/retirement-plans/plan-particip...When an IRA invests in real estate and the IRA does not have enough funds to fully purchased the property, the IRA can obtain a non-recourse loan.

@Dustin Verley  In addition to real estate notes I've also worked with these cash flows:Business Notes - no real estate as collateral just FFE  (furniture, fixtures & equipment) and goodwill.Mobile Home Only Notes - mobile home on rented lot so no real estateInvoices - buying accounts receivable at a discount.Cell Tower LeasesLand LeasesCasino or Jackpot payoutsLottery paymentsStructured SettlementsAnnuitiesI haven't personally worked with Auto notes but know several investors doing well in that arena as well.The basic concept with all of these options is similar (purchase a future cash flow at a discount using time value of money calculations or IRR) but the documentation and due diligence will differ.

This would be in addition to the CRIM, correct?
